Product Overview
Our Electronic Potting, also called potting glue or encapsulation silicone, is a high-performance Silicone Encapsulant specially engineered for EV charging stations—the core component ensuring safe, efficient charging for electric vehicles. As a professional supplier of Thermally Conductive Potting Compound and industrial silicone solutions, we optimize this product for EV charging scenarios: it bonds perfectly to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), with excellent waterproof, moisture-proof, corrosion-resistant, high-voltage insulation and shock absorption performance. It effectively protects charging station electronics from high voltage, high temperature, dust, rainwater and electromagnetic interference, ensuring safe, stable and efficient EV charging. Technical Specifications
Our Electronic Potting has stable performance with fully customizable parameters; key specifications: it is dual-component addition-curing liquid silicone (A and B), A component needs full stirring to mix settled fillers, B component needs thorough shaking. A/B weight ratio is adjustable; optional vacuum defoaming (0.01MPa for 3 minutes) before pouring. It supports room-temperature or heated curing, basic curing for next process, full curing within 24 hours (temperature and humidity affect curing). It operates continuously from -60℃ to 220℃, with high dielectric strength, low volatility, high strength, excellent adhesion and efficient thermal conductivity. Shelf life is 12 months sealed, non-hazardous for transportation. Product Features & Advantages

- Superior High-Temperature Resistance: Stable performance up to 220℃, rapidly dissipating heat generated during high-power, fast charging, protecting internal components from overheating and extending service life.
- Strong Waterproof & Dustproof: Excellent sealing performance, isolating rainwater, dust and moisture, adapting to outdoor and semi-outdoor EV charging scenarios, avoiding component damage.
- Anti-Electromagnetic Interference: Effectively shields electromagnetic interference, ensuring stable signal transmission of charging station controllers, avoiding charging failure or malfunctions.
- Strong Adhesion & Low Volatility: Bonds firmly to EV charging equipment materials, high structural strength; low volatile content, no contamination to precision electronic components, ensuring long-term stability.
- Dual Curing & Customizable: Available in addition-curing and condensation-curing types, adjustable curing speed and viscosity, adapting to EV charging station mass production workflows.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled fillers evenly, shake Component B thoroughly; slight stratification during storage does not affect performance after stirring.
- Component Mixing: Strictly mix A and B according to specified weight ratio, stir continuously until homogeneous for optimal curing, insulation and thermal conductivity.
- Vacuum Defoaming: Place mixed glue in a vacuum container, defoam at 0.01MPa for 3 minutes to remove bubbles, ensuring dense, bubble-free encapsulation and no insulation gaps.
- Curing Process: Pour defoamed glue into EV charging station components, cure at room temperature or heat. Proceed to next process after basic curing; full curing (24 hours) ensures optimal protective performance.
